The mother of a missing San Diego State University student who disappeared in Spain on Feb. 25 said she is certain her son will be found.

“I know he is coming home, we just need to find him,” Pamela Bice said Sunday night. “I have no doubt. He would never not come home, he would not do that to his roommates, his friends and his family.”

Police in Madrid continue searching for Austin Bice. No new information was released on Sunday about the investigation.

Bice, an international business student, arrived at Universidad Carlos III de Madrid in mid-January for the winter semester. The Torrey Pines High School graduate was last seen at a fast-food restaurant in the Puerta del Angel neighborhood of Madrid, according to Spanish police. The restaurant is about a 20 minute walk from the university. Friends and classmates grew concerned and alerted police that Bice was missing on Feb. 26.

The disappearance has been assigned to a special police unit, according to a staff member of U.S. Rep. Brian Bilbray, R-Solana Beach. Bilbray has been coordinating with the family, police and the American Embassy in Spain on the case.

Bice’s father, Larry Bice, arrived in Madrid on Thursday. He and Bice’s friends have been posting missing-person posters around the city.

Pamela Bice said that Larry Bice will meet Monday with Madrid’s chief of police to get information on leads into their son’s disappearance.

“The police are working really hard, we just want to make sure they share whatever leads they have with us,” Pamela Bice said.

The Agape House, a SDSU campus ministry organization, has scheduled a candlelight vigil for Bice Monday from 6 p.m. to 9:30 p.m. on the campus’ Free Speech Steps.
